Linus Torvalds	6fda5e5180	Initialize tree descriptors with a helper function rather than by hand. This removes slightly more lines than it adds, but the real reason for doing this is that future optimizations will require more setup of the tree descriptor, and so we want to do it in one place. Also renamed the "desc.buf" field to "desc.buffer" just to trigger compiler errors for old-style manual initializations, making sure I didn't miss anything.

Nicolas Pitre	21666f1aae	convert object type handling from a string to a number We currently have two parallel notation for dealing with object types in the code: a string and a numerical value. One of them is obviously redundent, and the most used one requires more stack space and a bunch of strcmp() all over the place. This is an initial step for the removal of the version using a char array found in object reading code paths. The patch is unfortunately large but there is no sane way to split it in smaller parts without breaking the system.

Junio C Hamano	cc44c7655f	Mechanical conversion to use prefixcmp() This mechanically converts strncmp() to use prefixcmp(), but only when the parameters match specific patterns, so that they can be verified easily. Leftover from this will be fixed in a separate step, including idiotic conversions like if (!strncmp("foo", arg, 3)) => if (!(-prefixcmp(arg, "foo"))) This was done by using this script in px.perl #!/usr/bin/perl -i.bak -p if (/strncmp$([^,]+), "([^\\"])", (\d+)$/ && (length($2) == $3)) { s\|strncmp$([^,]+), "([^\\"])", (\d+)$\|prefixcmp($1, "$2")\|; } if (/strncmp$"([^\\"])", ([^,]+), (\d+)$/ && (length($1) == $3)) { s\|strncmp$"([^\\"])", ([^,]+), (\d+)$\|(-prefixcmp($2, "$1"))\|; } and running: $ git grep -l strncmp -- '*.c' \| xargs perl px.perl Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Linus Torvalds	cf39f54efc	git reflog show It makes "git reflog [show]" act as git log -g --pretty=oneline --abbrev-cmit and is fairly straightforward. So you can just write git reflog or git reflog show and it will show you the reflog in a nice format.

Nicolas Pitre	eb8381c885	scan reflogs independently from refs Currently, the search for all reflogs depends on the existence of corresponding refs under the .git/refs/ directory. Let's scan the .git/logs/ directory directly instead. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Nicolas Pitre	9a13f0b71b	make reflog filename independent from struct ref_lock This allows for ref_log_write() to be used in a more flexible way, and is needed for future changes. This is only code reorg with no behavior change. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Junio C Hamano	c9a8992569	reflog gc: a tag that does not point at a commit is not a crime. Although unusual, tags can point at any object. Warning only once is fine, but warning every time about the same tag gets annoying. Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago

Junio C Hamano	9bbaa6cc68	reflog-expire: brown paper bag fix. When --stale-fix is not passed, the code did not initialize the two commit objects properly. Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Junio C Hamano	03840fc32d	Allow in_merge_bases() to take more than one reference commits. The internal function in_merge_bases(A, B) is used to make sure that commit A is an ancestor of commit B. This changes the signature of it to take an array of B's and updates its current callers. Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Johannes Schindelin	883d60fa97	Sanitize for_each_reflog_ent() It used to ignore the return value of the helper function; now, it expects it to return 0, and stops iteration upon non-zero return values; this value is then passed on as the return value of for_each_reflog_ent(). Further, it makes no sense to force the parsing upon the helper functions; for_each_reflog_ent() now calls the helper function with old and new sha1, the email, the timestamp & timezone, and the message.

Junio C Hamano	cd1f9c36be	reflog --fix-stale: do not check the same trees and commits repeatedly. Since we use the reachability tracking machinery now, we should keep the already checked trees and commits whose completeness is known, to avoid checking the same thing over and over again.

Junio C Hamano	1389d9ddaa	reflog expire --fix-stale The logic in an earlier round to detect reflog entries that point at a broken commit was not sufficient. Just like we do not trust presense of a commit during pack transfer (we trust only our refs), we should not trust a commit's presense, even if the tree of that commit is complete. A repository that had reflog enabled on some of the refs that was rewound and then run git-repack or git-prune from older versions of git can have reflog entries that point at a commit that still exist but lack commits (or trees and blobs needed for that commit) between it and some commit that is reachable from one of the refs. This revamps the logic -- the definition of "broken commit" becomes: a commit that is not reachable from any of the refs and there is a missing object among the commit, tree, or blob objects reachable from it that is not reachable from any of the refs. Entries in the reflog that refer to such a commit are expired. Since this computation involves traversing all the reachable objects, i.e. it has the same cost as 'git prune', it is enabled only when a new option --fix-stale. Fortunately, once this is run, we should not have to ever worry about missing objects, because the current prune and pack-objects know about reflogs and protect objects referred by them. Unfortunately, this will be absolutely necessary to help people migrate to the newer prune and repack. Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago

Junio C Hamano	58748293f6	reflog expire: do not punt on tags that point at non commits. It is unusual for a tag to point at a non-commit, and it is also unusual for a tag to have reflog, but that is not an error and we should still prune its reflog entries just as other refs.

Junio C Hamano	8d8b9f6252	reflog expire: prune commits that are not incomplete Older fsck-objects and prune did not protect commits in reflog entries, and it is quite possible that a commit still exists in the repository (because it was in a pack, or something) while some of its trees and blobs are long gone. Make sure the commit and its associated tree is complete and expire incomplete ones. Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Junio C Hamano	4264dc15e1	git reflog expire This prepares a place to collect reflog management subcommands, and implements "expire" action. $ git reflog expire --dry-run \ --expire=4.weeks \ --expire-unreachable=1.week \ refs/heads/master The expiration uses two timestamps: --expire and --expire-unreachable. Entries older than expire time (defaults to 90 days), and entries older than expire-unreachable time (defaults to 30 days) and records a commit that has been rewound and made unreachable from the current tip of the ref are removed from the reflog. The parameter handling is still rough, but I think the core logic for expiration is already sound. Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
